Title: Magnetic recorder
Inventor: ITO SUSUMU
IPC: G11B5/02
Filed: 1988-05-12
Abstract: PURPOSE:To improve the S/N of a reproducing signal by connecting an amplifier receiving feed from a solar battery to a magnetic head, and amplifying the reproducing signal of the head directly. CONSTITUTION:Four low-noise amplifiers 44 are provided in a low-noise amplifier unit 32 in a rotary drum 10, and are connected to the magnetic heads 12, 14, 16, and 18, and also, a rotary transformer as a signal transfer part is provided in the center part of the unit 32. When a VTR performs a reproducing operation, a light source 38 is lit and the solar battery 42 is irradiated to generate an electromotive force and it is supplied to the amplifier 44. The reproducing output of the magnetic head, after being amplified by the amplifier 44, is sent to a reproduction circuit via the rotary transformer 46. Therefore, since amplification is performed before the noise is mixed in the reproducing signal, the S/N of the reproducing signal can be improved.

Title: Laser diode driver
Inventor: TADA TOSHIO
IPC: H01S5/0683
Filed: 1988-05-11
Abstract: PURPOSE:To eliminate the influence of returning light quantity for a high output laser diode, to automatically perform constant optical output drive with a specified optical output, and to prevent a current injected to the laser diode from increasing and its quality from deteriorating by switching over between a photoelectric converter and a monitoring photodiode. CONSTITUTION:As a laser diode injecting current (b) supplied from a controller 10 to a laser diode 1 is increased proportionally to a time, an output voltage (c) from a photoelectric converter 4 and a photoelectric conversion voltage (e) from a monitoring photodiode 3 are similarly increased. The voltage (c) is inputted to the controller 10, compared with a reference voltage A (first reference voltage), the increase of the laser diode injecting current is stopped when the output voltage of the converter 4 coincides with the voltage A to hold its current value as it is. Then, a nonreflecting shutter 6 is closed by a signal (d), the monitoring photoelectric conversion voltage (e) obtained in this state is used as a reference voltage B (second reference voltage), and the laser diode injecting current (b) is so controlled that the monitoring output always becomes equal to the voltage B.

IPC: A23L27/30
Filed: 1983-06-29
Abstract: PURPOSE:To enable the utilization of molasses containing a specific component as a low-cariogenic hardly-crystallizable syrup, by treating a sucrose syrup with a palatinose-producing enzyme, converting more than a specific amount of sucrose to palatinose, separating the crystallized palatinose, and using the remaining liquid as the objective syrup.

Title: Cleaning device of electrophotographic copying machine
Inventor: WATANABE TOSHIO
IPC: G03G21/00
Filed: 1983-06-29
Abstract: PURPOSE:To obtain excellent cleaning effect for a long period and eliminate partial deterioration of a photosensitive body by constituting a brush body so that its front edge leaves the surface of the photosensitive body unless copying operation is in operation and is formed of fibers contacting the surface of the photosensitive body by centrifugal force according to rotation. CONSTITUTION:The brush body 3a of a cleaning body 3 has length l1 unless copying operation is in operation, and its front edge leaves the surface of the photosensitive body 1 slightly. The length increases to length l2 by the centrifugal force of rotation on the start of copying and untransferred toner remaining on the surface of the photosensitive body in contact is removed efficiently with a nip l3. Thus, the brush body is separate from the photosensitive body surface while the copying operation is not in process, so the surface never deteriorates locally and part of the brush does not weakens due to contacting, thereby maintaining the excellent cleaning effect for a long period.

Title: Production of multiplate type heat exchanger
Inventor: YOKO TAKEJI
IPC: C23C10/28
Filed: 1980-08-25
Abstract: PURPOSE: To lower the product cost of a heat exchanger by using copper-plated copper plates for plate blank materials, melting the copper and performing the formation of corrosion resistant alloy films and brazing at the time of producing a multiplate type heat exchanger by in-furnace brazing.  
     CONSTITUTION: Steel plates applied with 3-ply plating of Cu, Ni, Cu on both surfaces are worked to a flat tray shape to form upper and lower plates 2a, 2b, and fins 3 and reinforcing materials 4 are disposed in the inside. These are staked to form tubes 2, and are alternately superposed with short pipes 5, whereby a heat exchanger 1 is assembled. This is loaded into a vacuum furnace or a reducing gas atmosphere furnace, where it is heated under copper brazing conditions to allow the Cu in the plating layers to melt, thereby forming the Cu-Ni alloy layers of superior corrosion resistance. At the same time, the molten plating copper is utilized as a brazing filler metal. Costly materials such as monel metal and stainless steel are not required for the plate materials, and since no brazing filler metals are separately used, the heat exchanger is produced at low costs.

Title: Aperture plane antenna
Inventor: KUSANO MITSUHIRO
IPC: H01Q19/18
Filed: 1987-05-15
Abstract: PURPOSE:To improve a gain by almost uniformizing amplitude distribution at the aperture plane of a main reflecting mirror, by forming the main reflecting mirror in a rotational parabolic plane rotated around an axis in parallel with the axis including a focal point, and constituting a sub reflecting mirror of a first rotational parabolic plane arranged on a center side and setting the radiant point of a primary radiator as the focal point and a second rotational parabolic plane setting the focal point of the main reflecting mirror as the focal point. CONSTITUTION:All of the waves radiated from the primary radiator centering the focal point P, after being reflected on the first rotational parabolic plane 2a geometric-optically, become the waves advancing in a direction of X-axis, and are made incident on the second rotational parabolic plane 2b. Since a point F is set as the focal point on the second rotational parabolic plane 2b, the wave after being reflected is projected on the main reflecting mirror 1 as if it is the wave radiated centering the point F. In such a way. it is possible to eliminate the wave reflected on the primary radiator from the sub reflecting mirror 2 geometric-optically, and simultaneously, to arrange uniformly the phase of the wave reflected from the main reflecting mirror 1 as targeted. Simultaneously, as for the amplitude distribution, it can be almost uniformized at the aperture plane, and aperture efficiency, that is the improvement of the gain can be obtained.

Abstract: PURPOSE:To eliminate the noise due to electromagnetic sound by controlling a current flowing through a control side coil by a current controller and controlling the impedance of a load side coil. CONSTITUTION:When the resistance of a variable resistor 14 is zero, the synthetic resistance value of a load voltage regulator 32 is only the resistance value of a semi-fixed resistor 13, a current flowing through the base of a transistor 28 increases, and the current which flows from a DC power source circuit 21 through a resistor 34, between the collector and the emitter of the transistor 28 to the control side coils of reactors 26, 26' increases.

Title: Input switching circuit
Inventor: TAROUMARU MAKOTO
IPC: H03K17/693
Filed: 1992-05-11
Abstract: PURPOSE:To prevent an input switching circuit, which is not an operation object, from being turned on even when another input switching circuit is ON by constituting a circuit so as to simultaneously turn off also MOSFET and a bipolar transistor(TR) when the circuit is turned off. CONSTITUTION:When a control input terminal 108 is 0V, the bipolar TR 102 is cut off and the gate potential of the MOSFET 111 is 0V. When an output terminal 107, i.e., the source potential of the MOSFET 11 is higher than 0V and less than DC power supply voltage Vb, the drain potential of the MOSFET 111 is higher than the source potential, the gate potential is negative against the source potential and no channel is formed. Since between the substrate and drain of the MOSFET 111 is reversely biased since the potential of the drain is higher than that of the substrate, no current flows into the substrate terminal of the MOSFET 111. Thereby impedance between the drain and source of the MOSFET 111 becomes high impedance and the input switching circuit 4 is turned to an off state.
